Abstract

A flexible organic light emitting display device includes a substrate having a display area and a side sealant pattern covering a portion outside the display area, wherein the side sealant pattern has a first width and a second width narrower than the first width, in the side sealant pattern, a pattern with the first width and a pattern with the second width alternate.

First claim

What is claimed is:

1. A flexible organic light emitting display device comprising:
a substrate having a display area and a non-display area; and
a side sealant covering a portion of the substrate in the non-display area,
wherein the side sealant is disposed in a pattern having a first width and a second width narrower than the first width, the first width and the second width being alternately arranged with respect to one another in a direction in which a force acts when the substrate is rolled or folded.

2. The flexible organic light emitting display device of claim 1 , wherein the side sealant pattern includes a third width that is narrower than first width and different from the second width, and the side sealant pattern includes a first portion having the first width and the second width and a second portion having the first width and the third width, the first and second portions being alternately arranged with respect to one another.

3. The flexible organic light emitting display device of claim 1 , wherein opposing sides determining the first width and opposing sides determining the second width are connected by curved lines, respectively.

4. The flexible organic light emitting display device of claim 1 , wherein opposing sides determining the first width and opposing sides determining the second width are connected by linear lines, respectively.

5. The flexible organic light emitting display device of claim 1 , further comprising:
a hollow region extending through an inside portion of the side sealant pattern.

6. The flexible organic light emitting display device of claim 1 , further comprising:
an encapsulation layer covering the display area,
wherein the side sealant pattern is in contact with a side surface of the encapsulation layer.

7. The flexible organic light emitting display device of claim 6 , further comprising:
a flexible film bonded to at least one side of the non-display area,
wherein the side sealant covers an upper surface of an edge of the flexible film.

8. A flexible organic light emitting display device comprising:
a flexible substrate having a display area and a non-display area;
an encapsulation layer covering the display area;
a flexible film bonded to the substrate in the non-display area; and
a sealant in the non-display area, the sealant covering at least a portion of the flexible film and contacting a side surface of the encapsulation layer, the sealant extending lengthwise in a first direction in the non-display area and widthwise in a second direction that is perpendicular to the first direction, the sealant including:
a plurality of first sections having a first width, and
a plurality of second sections having a second width that is narrower than the first width, the second sections being positioned between respective first sections

wherein the first sections and the second sections are alternately arranged with respect to one another in a direction in which a force acts when the flexible substrate is rolled or folded.

9. The flexible organic light emitting display device of claim 8 , wherein the sealant has a curved outer shape between the first sections and the second sections.

10. The flexible organic light emitting display device of claim 8 , wherein the sealant has a linear outer shape between the first sections and the second sections.

11. The flexible organic light emitting display device of claim 8 , wherein the sealant includes a hollow region extending through an inner portion of the sealant.
